Interconnected rotary system with built-in suspension for baby prams

ABSTRACT

An interconnected rotary system with built-in suspension is provided for baby prams, intended to provide a use of only two wheels with interconnected steering. This system consists of two rotary suspension blocks ( 2 ) supporting the wheels ( 1 ) fixed to the chassis on (X) with a suspension spring ( 5 ) inside the rotary block ( 2 ) and with the rotary points (Y) on which a steering bar ( 3 ) is articulated. This new system will allow the use of larger wheels, increasing both the baby and user&#39;s comfort.

[0001] The present Patent refers to an interconnected rotary system with built-in suspension for baby prams.

[0002] Several rotary wheel systems with suspension are already known, with the normal use of four front wheels, two on each block to maintain balance and operating as a rotary wheel and completely independent.

[0003] Also, rotary systems exist with a single rotary type wheel, but also completely independent.

[0004] The present Patent provides the use of only two wheels with interconnected steering.

[0005] This new system will allow the use of larger size wheels, increasing the baby and user's comfort, since handling of the seat becomes easier.

[0006] The wheels are fixed to the front legs of the chassis and are fastened on blocks.

[0007] The blocks fit in the parts serving as the chassis bracing, said blocks being interconnected by a rod with two rotary points, making the two front wheels to become interlocked.

[0008] The present Patent is illustrated by a set of drawings which make part of the present specification and which with illustrative and non-limiting character show a preferred embodiment, where:

[0009]FIG. 1 shows a schematic side view of a baby's seat with the system according to the present Patent.

[0010]FIG. 2 shows a schematic detailed view of the rotary system according to the present Patent.

[0011]FIG. 3 shows a detailed view of a wheel support block.

[0012]FIG. 4 shows a schematic view with details of the optional wheel blocking system.

[0013]FIG. 1 shows a baby pram where (A) forms the pram handle, (Z) the support and articulation of the front and rear legs, (7) the front leg of the chassis and (1) a wheel of larger size than those used until now.

[0014]FIG. 2 schematically shows the interconnected rotary system according to the Patent, in which the front legs of the chassis (7) support on (X) the suspension blocks (2) of the wheels (1).

[0015] On (X) are also supported the connection parts (8) in which the bracing bar (4) of the chassis is fitted.

[0016] On the suspension blocks (2), there are the rotary points (Y), which serve as a support to the rod (3) providing the interlocking interconnection of the wheels (1).

[0017]FIG. 3 shows a section of a suspension block (2) with a suspension spring (5).

[0018]FIG. 4 shows a section of the front leg of the chassis (7) inside of which a tie may operate in (Z) to make the wheel (1) to be blocked through the sliding device with a spring (6).

[0019] The operation of this blocking system may be carried out manually. 

1. INTERCONNECTED ROTARY SYSTEM WITH BUILT-IN SUSPENSION FOR BABY PRAMS, characterized in that it is comprised by two rotary suspension blocks (2) with the suspension springs (5) which support the wheels (1), joined on (x) to the chassis (7), having rotary points (y) on which a steering bar (3) is articulated.
 2. INTERCONNECTED ROTARY SYSTEM WITH BUILT-IN SUSPENSION FOR BABY PRAMS, according to claim 1, characterized in that it has the possibility of being blocked manually or by means of a tie inside the front leg of the chassis (7) through a sliding spring device (6) which acts on the wheel rim (1).
